Xam tawm qhov txawv ntawm qhov nqus plating thiab dej plating
Nov 14, 2018| Xam tawm qhov txawv ntawm qhov nqus plating thiab dej plating
Yog tias ib tug neeg nug koj, dab tsi yog electroplating? Koj yuav hais li cas? Muaj qee tus hais tias dej plating, qee tus hais tias nqus plating. Uas yog txoj cai? Qhov tseeb, "electroplating" txhais tau hais tias muaj ntau yam hauv cov lag luam. Piv txwv, nyob rau hauv txoj kev lag luam xov tooj txawb xov tooj tam sim no, muaj ob peb daim ntawv sau npe ntawm cov dej siv electroplating. Hauv ntau tus neeg lub hlwb, electroplating feem ntau yog hais txog lub tshuab nqus tsev vacuum, thaum nyob hauv kev lag luam zoo nkauj, dej electroplating yog siv ntau, ntawm chav kawm, hom electroplating hais txog dej electroplating. Ob qho dej electroplating thiab nqus plating yog mus rau electroplating film. Cia peb pib ntawm kev faib tawm ntawm cov yeeb yaj kiab, thiab pom qhov txawv ntawm ntau hom txheej.
Electroplating khoom yog cais raws li nram no raws li txoj kev tsim:
1. Phem theem: ---> hloov pauv;
2. Cov kua ua kua: ---> kev hloov tshuaj
3. Txoj kev ntsuas huab cua: -> kev hloov tshuaj thiab lub cev
Cov dej num raws li nram no:
Cov txheej txheem muaj xws li: dej plating, anodization, evaporation nqus, qhov nqus pa thiab xos plating.
Dej plating:
Keywords: anodic dissolution, cathode txuas, electrochemical cov tshuaj tiv thaiv
Cov txheej txheem dej electroplating yog siv los tsim cov teebmeem reflector thiab nce adhesion txheej, thiab lwm yam zoo. Qhov zoo yog qhov loj ntawm plating, raug nqi tsawg, muaj tshuaj lom neeg muaj roj ntsha thiab muaj paug loj muaj paug.
Dej ntim kab
Anodic oxidation txheej txheem :
Keywords: hlau oxide zaj duab xis, hluav taws xob tshuaj
Anodic oxidation kuj tuaj yeem ua tau rau hauv Ta2O2, TiO2, ZrO2, Nb2O5, HfO2, WO3, thiab lwm yam., Tau siv los ua cov yeeb yaj kiab los yog xim cov xim zaj duab xis.
Anodized khoom
Lub tshuab nqus tsev evaporation tseem hu ua thermal evaporation
Txheej txheem cov lus tseem ceeb: kub kub yaj evaporation, deposition tom qab npog zaj duab xis
Raws li qhov sib txawv cua sov txoj kev ntawm cov ntaub ntawv zaj duab xis, lub tshuab nqus tsev vacuum yuav muab faib ua hom tsis ua hauj lwm hom thiab cov cua sov hom.
1. Cov hom phiaj ncaj qha rau cua sov: tsuas yog rau cov evaporation source, tsis ncaj qha rau ua cov ntaub ntawv zaj duab xis rau nws kom qhuav thaum kub;
2. Muab cov cua sov ncaj qha: siv cov khoom siv hluav taws xob (electron beam, plasma los yog laser) los yog kev sib txuam ua kom sov siab rau cov khoom siv yees duab ntawm cov hmoov evaporation thiab evaporate; *
Yuav kom tsis txhob evaporation ntawm lub hauv paus (thawv) nrog rau cov khoom siv zaj duab xis, lub pob zeb ntawm qhov khoom siv yuav tsum siab tshaj lub ntsiab lus ntawm cov yeeb yaj kiab.
Evaporation txujci
Kev ua kom sov thiab cua ntsev
Cov khoom siv zaj duab xis yog cov tsis muaj zog los ntawm thermal lub zog tsim los ntawm cov hluav taws xob tam sim no dhau los ntawm kev tawm tsam. Tus ntaus ntawv yog raws li nram no:
Kev ua kom sov thiab cua ntsev
Disadvantages ntawm ua cua sov:
1. Nws yog ib qho tsim nyog kom ua kom cua sov los ua ntej hloov mus rau hauv cov khoom siv zaj duab xis. Cov evaporation yog ib qho yooj yim los ua rau cov khoom los yog hlau lead;
2. Cov cua kub ntawm cov evaporation yog qhov tsawg, thiab feem ntau ntawm cov oxide ntawm high point melting tsis tau yaj thiab evaporated;
3. Tsawg evaporation ceev;
4. Yog hais tias cov khoom siv lo yog ib qho chaw, nws yuav tsum tau decomposed;
5. Cov yeeb yaj kiab tsis yog qhov nyuaj, nrog kev ceev tsawg thiab kev tsis zoo.
Sputtering lo
Keywords: ionized ionized roj, target bombardment, target peeling, deposition, txias, zaj duab xis tsim
Lub hauv paus ntawm lub tshuab ua kom tshuab pa yog qhov ua kom siv pa tawm hauv lub tshuab nqus tsev, ncaj qha los ntawm cov khoom siv (lub hom phiaj) raws li cov electrodes, siv cov electrodes saib hluav taws xob 5 kv ~ 15 kv plasma bombardment ntawm cov khoom siv, qhov cua nkag nrog roj tib lub sijhawm, roj ionization, tsiv raws li cov ntsiab lus nyob rau hauv cov ntshav, cov khoom siv rau cov khoom phom sij thiab cov khoom siv hauv tsev uas tso rau saum npoo av, kom txias rau hauv ib lub yeeb yaj kiab.
Magnetron Txiav Tso Tseg
Cov qauv ntawm cov electrode tau zoo dua los ntawm dc los yog lub xov tooj cua zaus zawm, uas yog, ib qho chaw ruaj khov nyob hauv sab hauv ntawm lub cathode, thiab qhov sib txawv ntawm qhov sib txawv ntawm cov hluav taws xob hauv cheeb tsam tsaus, raws li tswj cov kev lag luam ntawm cov nqi uas muaj nrog cov sib nqus field. Qhov no yog txoj kev hu ua magnetron sputtering .
Magnetron sputtering schematic daim duab
Raws li qhov quab yuam ntawm cov hlau nplaum yog qhov ncaj rau cov kev taw qhia ntawm electrons, qhov centripetal quab yuam ntawm electron cyclogenesis yuav raug tsim. Nyob rau lub sij hawm no, qhov tshwm sim ntawm kev sib tsoo nruab nrab ntawm cov hom tsis muaj zog, thiab nyias cov yeeb yaj kiab tuaj yeem ua rau tsis tshua muaj siab.
Dhau li tsis tshua muaj siab, qhov ob qhov zoo ntawm magnetron sputtering yog kev kub ceev thiab tsawg dua.
Tab sis magnetron sputtering kuj muaj qee cov teeb meem, xws li kev siv hlau nplaum hluavtaws hluav taws xob, electrode magnetic tswj electrode, lub ntsiab ntawm lub hauv paus thiab peripheral tsis yog sibpab ntawm cov hlau nplaum sib txuas ntawm cov hluav taws xob ntau ntau thiab me me, piv txwv li mus tib seem ntawm lub hom phiaj ntawm cov hlau nplaum magnetic tiv thaiv kab mob me me, nyob hauv ib cheeb tsam ntawm qhov chaw ntawm cov khoom siv los ntawm kev siv qaub ncaug ceev nrawm, thaum lub hauv paus thiab ntug nqus qis dua, yog li nws yuav yog lub vos zoo li erosional hav, txo qhov kev siv cov khoom ntawm cov khoom, thiab yuav cuam tshuam cov yeeb yaj duab tsis meej.
Ion plating txoj cai
Ion Plating
Ntsiab lus: nqus cov pa roj paug, tawm ntawm qhov chaw, cov khoom tawg pob khoom
Lub hauv paus ntsiab lus tseem ceeb yog muab cov khoom siv mus rau hauv ib lub xeev los ntawm kev siv cov pa tawm ntawm qhov ua pa tawm thiab tom qab ntawd tso rau ntawm lub substrate.
Qhov yooj yim electroplating system rau ion plating yog PVD system, uas tsuas ntxiv cov roj gaseous ua kom nws hnov mob nrog cov khoom siv zaj duab xis tom qab evaporation thiab ces tso rau hauv lub substrate los tsim tebchaw. Yog li ntawd, lub composition ntawm zaj duab xis lo yog txawv los ntawm thawj zaj duab xis cov khoom, thiab nws yog ib tug compound ntawm puag ntaub ntawv.
Ion plating yeej muaj peb kauj ruam:
1. Transforming cov atomic acid rau hauv lub cev muaj zog: ntau yam evaporation cov chaw thiab ntau yam tshuab raj phev yuav ua tau kom nqus evaporation kom ua tiav lub hom phiaj no;
2. Hloov cov xaim hluav taws xob ua rau hauv cov xeev ionic los ua kom muaj qhov txawv ntawm ionization ntawm cov khoom siv raw (feem ntau yog txog 1) . Ntau yam ntawm ion ntsiab yuav siv los hloov lwm lub zog rau cov khoom siv raw lub cev ua kom tiav qhov kev ntsuas ionization thaum pib;
3. Ua kom lub zog ntawm cov ionic khoom los txhim kho qhov zoo ntawm zaj yeeb yaj kiab: qhov peev xwm ntawm kev ceev cov ions tuaj yeem ua tiav los ntawm kev muab ntxiv rau kev tsim nyog tsis zoo .
Cov yam ntxwv ntawm ion plating yog raws li nram no:
1. Ion plating tuaj yeem nqa ntawm qhov kub ntawm 600 degrees;
2. zoo adhesion;
3. Zoo diffracted - them atomic zog tuaj txog tag nrho cov theem pib yooj yim thiab tso cov txheej;
4. Qhov ceev ceev yog ceev ceev, mus txog 1 ~ 5um, thaum lub sij hawm qaub ncaug zog ntawm lub phaj thib ob tsuas yog 0.01 ~ 1.0um / min;
5. Cov khoom ua thiab kev xaiv ntawm cov khoom siv nyias zaj duab xis yog qhov dav. Dhau li ntawm co, ceramics, iav thiab plastics yuav ua tiav.
PVD peb pawg ntawm cov yam ntxwv kev sib piv
Saum toj yog qhov yooj yim combing ntawm txheej txheej txheej. Yog hais tias koj xav muab cov ntsiab lus nthuav ntxiv, koj tuaj yeem tawm hauv xov ntawm qhov kawg ntawm tsab xov xwm.
